Note the following excerpt, reflecting upon if such conclusions might also serve our face-to-face classrooms as well:
In a paper published this spring, the CSAIL team outlined some key findings on what online learners want from videos. These include:
- Brevity (viewers generally tune out after six minutes)
- Informality, with professors seated at a desk, not standing behind a podium
- Lively visuals rather than static PowerPoint slides
- Fast talkers (professors seen as the most engaging spoke at 254 words per minute)
- More pauses, so viewers can soak in complex diagrams
- Web-friendly lessons (existing videos broken into shorter chunks are less effective than ones crafted for online audiences)
